IMPROVEMENT lN BELT-SHIPPING MECHANISMS FOR LOOMS.

Specification forming part of Letters Patent No. 198,202, dated December18, 1877; application filed November 3, 1877.

To all whom it may concern:

Be it known that I, Lucius J. KNowLEs, of the city and county ofWorcester and Commonwealth of Massachusetts, have invented certain newand useful Improvements in Shippers for Power-Looms; and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, forming apart of this specification, and in which Figure 1 represents a top orplan view of so much of a loom as is necessary to illustrate my presentinvention. Fig. 2 represents a side view of the parts shown in Fig. 1;and Fig. 3 represents a top or plan view of a portion of the parts shownin Fig. 1, one of the shipper-handles being shown in section on line AB, Fig. 2.

To enable those skilled in the art to which my invention belongs to makeand use the sanlne, I will proceed to describe it more in detai In thedrawings, the part marked A represents one side of a loom-frame, towhich are secured the bearings B B for the shaft 0, upon the end ofwhich are to be secured, in the usual manner, the tight and loosepulleys.

D is the shipper-rod, to which is secured the shipper-fork E, by meansof a set-screw, a. The shipper-rod D passes loosely through aguide-piece, b, said guide-piece being rigidly secured to the side ofthe loom-frame; and between said guide-piece and the shipper-fork aspiral spring, F, is arranged upon the shipperrod D.

The fiont end of shipper-rod D is hinged to the long arm of a bell-crankor connecting lever, G, pivoted at d to a stand, H, fastened to the sideof the loom, while the short arm 6 of the bell-crank is provided with apin, f, which projects up and passes through a slot, g, provided with anotch or recess, h, in the foot I of the shipper-handle J, saidshipper-handle being secured to a rod, K, which passes through under thebreast-beam L, so that it can be operated from either side of the loom.

The upper end of shipper-handle J is shown broken off in Fig.2; but itwill be understood that it is to have a suitable hand-piece, as shown inFig. 1, and the opposite end of rod K, on the opposite side of the loom,is also to be provided with a suitable handle, so that shipper-rod D canbe operated by means of the slotted foot I from either side of the loom.

When shipper-fork E is to be drawn toward the loom-frame for the purposeof throwing the belt upon the tight pulley, the operative takes hold ofshipperhandle J and draws the upper end forward, thereby throwing foot Iback, as shown in dotted lines, Fig. 3, and by which operation pin f isforced toward the loom-frame, thereby drawing the long arm 0 ofbell-crank or connecting lever Gr forward, together with shipper-rod D,as indicated in dotted lines, Fig. 3; and when the parts are in thisposition, pin f rests in the recessed or notched portion h of slot 9,and the action of spring F upon shipper-rod D holds the parts in suchrelative positions until the operative, taking hold of the upper end ofhandle J, forces it back until pin f has been released from the recessedpart h, when the action of spring F throws the shipper-rod D, with itsfork E, back into the position shown in full lines, Figs. 1 and 2, thusthrowing the belt upon the loose pulley again.

It will be observed that slot 9 is cut at an angle with the side of theloom, so that it acts upon pin f in the form of a cam, thereby rotatingor swinging bell-crank or connectinglever Gr upon its pivot (1 until pinf reaches and enters the notched or recessed part h in said slot, whenpin f reacts upon the slotted foot I in such a manner as to force andkeep it back in the position shown in dotted lines, Fig. 3, until, asbefore explained, the operative removes, by means of handle J, pin ffrom the notched or recessed part h of said slot g.

In very narrow looms rod K may be dispensed with, and a projecting studsubstituted for supporting shipper-handle J, said stud being properlysecured to the loom-frame; and in cases where the belt-shaft G isarranged upon the loom at right angles to the position shown in thedrawings, a straight connecting lever, Gr, would be used instead of abell-crank connecting-lever, since the direction of the motion ofshipper-r03. D would be at right andie J, provided with notched andslotted. foot gles to its present motion.
